IX. CONCLUSION
The paper has reviewed the reported literature on wearable
sensors and devices for monitoring human activities. The
human activity monitoring is a vibrant area of research and
a lot of commercial development are reported. It is expected
that many more light-weight, high-performance wearable
devices will be available for monitoring a wide range of
activities. The challenges faced by the current design will
also be addressed in future devices. The development of
light-weight physiological sensors will lead to comfortable
wearable devices to monitor different ranges of activities of
inhabitants. Formal and Informal survey predicts an increase
of interest and consequent usages of wearable devices in near
future, the cost of the devices is also expected to fall resulting
in of wide application in the society
